HOLDER WITH TEAR-OFF MECHANISM FOR WEB-LIKE MATERIAL This is acontinuation, of application Ser. No. 370,575 filed June 15, 1973, nowabandoned.

BACKGROUND OF THE INVENTION The present invention relates to a new andimproved construction of holder equipped with a tear-off mechanism forweblike material, especially paper rolls, and which paper roll holdercomprises a supportingand holding portion for the material with abearing surface. The material is withdrawn through the bearing surfaceand the tear-off mechanism is arranged following the bearing surface.

Paper roll holders of the previously mentioned type are known to theart. Normally they possess the form of a container at the floor of whichthere is provided an opening through which the paper withdrawn from thepaper roll is guided. With a particularly advantageous constructionalembodiment the container is downwardly extended passed the floor orbottom, this extension tapering conically towards the inside. At thelower end of the extension there are located tear-off or tearing teeth.It has been found that with the paper web torn-off it is very difficultto again seize the same and to draw such through the outlet opening inthe aforementioned extension. When attempting to seize the paper stripit often happens that the user injures his fingers at the roll holder.

SUMMARY OF THE INVENTION Hence, it is a primary object of the presentinvention to provide an improved construction of holder for weblikematerial equipped with a tear-off mechanism and which is not associatedwith the aforementioned drawbacks and limitations of the prior artconstructions.

Another object of the present invention aims at an improved constructionof holder for web-like material which is relatively simple inconstruction and design, easy to use, and economical to manufacture.

Now in order to implement these and still further objects of theinvention, which will become more readily apparent as the descriptionproceeds, the holder with the tear-off mechanism of this development ismanifested by the features that the tear-off mechanism consists of atubular section protruding from the bearing surface. The tubular-shapedtear-off mechanism is advantageously constructed as a separate componentand connected at the bearing surface for the material in any suitableway, such as by threading, a bayonet connection or lock or the like. Thetear-off mechanism can be of cylindrical configuration or can conicallywiden in the throughpassage direction of the paper.

Owing to the construction of the tear-off mechanism as contemplated bythis development it is possible to positively seize a paper end whichhas been torn without danger of injury and to draw such out of the paperroll holder and its tear-off mechanism respectively.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be betterunderstood and objects other than those set forth above, will becomeapparent when consideration is given to the following detaileddescription thereof. Such description makes reference to the annexeddrawings wherein:

FIG. 1 is a schematic view of a paper roll holder having a tear-offmechanism and designed according to the teachings of the presentinvention;

FIG. 2 is a further exemplary embodiment of paper roll holder embodyingteachings of the inventionj FIG. 3 is a variant embodiment of paper rollholder.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Describing now thedrawings, it will be recognized that the paper roll holder depicted byway of example in FIG. 1 comprises a supporting and holding portionincorporating a bearing or,support plate 1 for supporting a paper roll 2as well as a holding bracket 3 which has a flexed free end 3 whichengages into a central opening of the paper roll 2 and in this waypositively retains the roll against the bearing or support plate 1. Thisbearing plate 1 will be further understood to possess at its centralregion an outfeed opening 4 through which there can be downwardly drawna paper strip 2 from the roll 2. From the region of this opening 4 theredownwardly extends a substantially tubular-shaped tear-off mechanism5..An essential aspect of this embodiment of tear-off mechanism 5resides in the fact that the tubular member or tube 5a, viewed in thethroughpassage or throughflow direction of the paper 2', conicallywidens. In this way it is possible to engage with the hand or thefingers of the user into the confines of the tubular-shaped tear-offmechanism 5 and to seize the end of the paper strip in that it is pushedagainst the inner wall of the tubular member 5a and at the same timedpulled downwardly. Owing to the particularly simple possibility ofseizing the paper strip injury to the user by virtue of the tear-offteeth 5' provided at the lower end of the tubular member 5a ispractically eliminated.

The bearing plate or bearing surface 1 could of course consist ofindividual arms, such as generally indicated by reference character 1a,arranged in a starlike configuration with regard to the opening 4. Thetubular-shaped tear-off mechanism 5 can be formed as a separatecomponent or integrally with the bearing plate or surface 1 and theactual paper roll holder.

FIG. 2 of the drawings illustrates a variant of the inventive paper rollholder wherein in this case the actual supportingand holding portion ofthe roll holder consists of a container 6 with a detachable cover 7. Atthe floor of the container 6 there is also here provided an opening 8through which there can be withdrawn a paper strip 9' of the paper roll9. Following this opening 8 there is arranged the tubular-shapedtear-off mechanism 10 which conically widens in the throughpassagedirection of the paper. The tear-off mechanism 10 is further surroundedby a covering sleeve or jacket 1 1 which, for instance, can be fixed tothe container 6 and the tube or tubular member 10a. An essential aspectof this exemplary embodiment of the invention likewise resides in thefact that the tubular-shaped tearoff mechanism 10 conically downwardlywidens, thereby enabling positively seizing at any time the paper striplocated internally of the tubular member and without danger of injurydrawing such past the tear-off teeth 10'.

FIG. 3 illustrates a cross-sectional view of a further embodiment ofpaper roll holder designed according to the invention having a tear-offmechanism 11'. Here the tear-off mechanism 11' is constituted by acylindrical tubular member 11a which can be threaded by threading 11binto the threaded bottom or floor opening 12 of the bearing surface orbearing plate 13 of the supporting and holding portion 15. Attachment ofthe tear-off mechanism 11, constructed in this instance as a separatecomponent, can also be accomplished for example, by means of a bayonetclosure or lock. Such type disconnectible attachments have the notableadvantage that depending upon the environment of use, and specificallythe nature of the tearable paper and its degree of difficulty to tear,there can be employed different tear-off mechanisms provided withsuitable teeth.

While there is shown and described present preferred embodiments of theinvention, it is to be distinctly understood that the invention is notlimited thereto, but may be otherwise variously embodied and practicedwithin the scope of the following claims. Accordingly,
